Engineering photon statistics in a spinor polariton condensate
Stepan Baryshev, Anton V. Zasedatelev, Helgi Sigurdsson +4
We implement full polarization tomography on the photon correlations in a spinor exciton-polariton condensate. Our measurements reveal condensate pseudospin mean-field dynamics spa…
Polariton spin jets through optical control
Lucinda Pickup, Julian D. Töpfer, Helgi Sigurdsson +1
We demonstrate spin polarized jets in extended systems of ballistic exciton-polariton condensates in semiconductor microcavities using optical non-resonant excitation geometries. T…
Engineering spatial coherence in lattices of polariton condensates
Julian D. Töpfer, Ioannis Chatzopoulos, Helgi Sigurdsson +3
Artificial lattices of coherently coupled macroscopic states are at the heart of applications ranging from solving hard combinatorial optimisation problems to simulating complex ma…
Solving the max-3-cut problem using synchronized dissipative networks
Stella L. Harrison, Helgi Sigurdsson, Sergey Alyatkin +2
Many computational problems are intractable through classical computing and, as Moore's law is drawing to a halt, demand for finding alternative methods in tackling these problems…
Quantum fluids of light in all-optical scatterer lattices
Sergey Alyatkin, Helgi Sigurdsson, Alexis Askitopoulos +2
One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificially constructed potentials, giving insight into physical phenome…
